Question

1- Write five rational numbers:
2 - Write five irrational numbers

Answer 1

`\text{Rational numbers are those real numbers which can be written in the form of }\\\text{fraction, where denominator cannot be zero and both numerator and}\\\text{denominator should be integer. For example, }(2)/(3)\text{\ is a rational number because}\\\text{2 and 3 are integers and }3\\e0.\text{\ An integer is a rational number that can be }\\\text{written without a decimal or fractional part.}`

`\text{Other examples of rational numbers are: 3, -5, }-(10)/(3),\ 5.6,\ 0, \text{\ etc.}`

`\text{Irrational numbers are those real numbers which cannot be expressed in }\\\text{fractions of two integers.}\\\text{Some examples of rational numbers are: }\pi,\ \text{Euler's number}(e),{\sqrt2},\ \sqrt[3]{7},\sqrt[4]{5}\\\text{etc.}\\`

`√(4)\ \text{is not irrational because it's equal to 2, which is a rational number.}`

`\text{Given below is the family tree of real numbers. Read it carefully, then you will}\\\text{understand better.}`
